Makefile:18: *** Kernel version not found, maybe you need to install appropriate kernel-headers or run make with KERNELSRC parameter, e.g.: make KERNELSRC=/usr/src/linux. Stop.

As a workaround you can delete all the lines with ".owner = THIS_MODULE" that cause these errors as a temporary workaround - but be sure NOT to remove the one line with .owner that does not trigger an error.

However, I am working on an updated version of phc-k8, but I'm still working on it to make it support older kernels. I am striving to be uploading a test-release soon, but I have no clue what kernel versions need to be supported, see my call for feedback on this forum... Initially I will probably only be supporting kernels from 2.6.32.y to 2.6.36.y.

By the way, this version of the driver will not yet be supporting undervolting family 10h and 11h processors (Phenom/Phenom II/Athlon II/Turion64/Turion II) since I have to rework some of that code first.

mperf.ko is an additional module that has been added to powernow-k8 since kernel 2.6.35 and therefore has been added to phc-k8. Basically it's used for intelligently handling the "Turbo Core" feature in AMD processors that support it. I added it because I wanted to use the latest powernow-k8 code and include as much code as reasonably possible. Also, it needs to be there if the driver is going to support undervolting Turbo Core processors, but I'm still waiting for someone that has one...
